Fix: remember the current schedule

[blundell]

Currently when you toggle charging on and off from HomeAssistant, it replaces whatever current schedule you have with a schedule of 00:00 - 00:01.

This change passes the Pod details in an attempt to retain the current schedule (by re-using whatever schedule was on the first day for every day).

• Passes on the schedule from the current pod
• Uses the times from the first scheduled day for all days

(N.b. I haven't done any actual testing of this change - its more of a suggestive change, if you could validate the idea 😄)

Thanks for your contribution, this is a really great enhancement, I'm fixing support for charge overrides but once that's in place I'll work on this slightly, I should be able to support keeping all the schedules rather than just copying day 1 through the whole week
